Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a parallel identification method and identification architecture for multi-channel heterogeneous optical fiber data. Background Technology

[0002] In the field of communication data identification, operators need to quickly identify the format types of data from different access optical fibers. Currently, most methods for identifying heterogeneous optical fiber data format types adopt a serial identification scheme. However, under the current serial identification technology, identifying the format types of all access data requires a relatively large number of steps, and the average identification time increases significantly, especially as the number of data format types increases. Summary of the Invention

[0003] This application proposes a parallel identification method and architecture for multi-channel heterogeneous optical fiber data, which solves the problem of low efficiency in existing serial identification technology.

[0004] This application provides a parallel identification method for multi-path heterogeneous optical fiber data, including the following steps:

[0005] S1: Output multiple heterogeneous fiber data in batches to n sets of format recognition modules for format recognition. The number of heterogeneous fiber data output in any batch is m, and m≤n.

[0006] S2: m heterogeneous fiber data are input one-to-one into m sets of format recognition modules, and format recognition is performed simultaneously;

[0007] S3: If the format of all m heterogeneous optical fiber data is identified, output the identification result and complete the format identification for this batch;

[0008] S4: If the format of m heterogeneous fiber data is not fully recognized, the m heterogeneous fiber data is shifted clockwise in n sets of format recognition modules, and then the format recognition of the shifted m heterogeneous fiber data is performed simultaneously again until the format of m heterogeneous fiber data is fully recognized, or until each heterogeneous fiber data has traversed all n sets of format recognition modules to complete the format recognition of this batch.

[0009] S5: Repeat steps S1 to S4 to complete the batch format recognition of multi-channel heterogeneous fiber optic data.

[0010] In some embodiments, step S4 further includes: if the format of m heterogeneous fiber data is not fully identified, the result of the heterogeneous fiber data with the identified format is output, the heterogeneous fiber data with the unidentified format is shifted clockwise in n sets of format identification modules, and then the format of the shifted heterogeneous fiber data is simultaneously identified again. This process is repeated until the format of all m heterogeneous fiber data is identified, or until all the heterogeneous fiber data with the unidentified format is traversed through n sets of format identification modules to complete the format identification of this batch.

[0011] In some embodiments, the heterogeneous fiber data is in formats including OTN, SDH, and ETH.

[0012] In some embodiments, the rates of the heterogeneous fiber data in the OTN format include 100G, 10G, and 2.5G.

[0013] In some embodiments, the rates of the heterogeneous fiber data in SDH format include 10G, 2.5G, 622M, and 155M.

[0014] In some embodiments, the rate of the heterogeneous fiber optic data in ETH format includes 10G and 1G.

[0015] This application also provides a parallel identification architecture for multi-path heterogeneous optical fiber data, including:

[0016] The format recognition unit includes n sets of format recognition modules, which are used to recognize the format of heterogeneous optical fiber data.

[0017] The fiber optic signal scheduling unit is used to output multiple heterogeneous fiber optic data in batches to n sets of format recognition modules for format recognition. The number of heterogeneous fiber optic data output in any batch is m, and m≤n.

[0018] If the format of all m heterogeneous optical fiber data is identified, the format identification module outputs the identification results respectively, thus completing the format identification of this batch;

[0019] If the format of m heterogeneous fiber data is not fully identified, the fiber signal scheduling unit will shift the m heterogeneous fiber data clockwise through n sets of format identification modules. Then, the format identification module will simultaneously identify the format of the shifted m heterogeneous fiber data again until the format of all m heterogeneous fiber data is identified, or until each heterogeneous fiber data has traversed all n sets of format identification modules to complete the format identification of this batch.

[0020] In some embodiments, if the format of m heterogeneous fiber data is not fully identified, the format identification module outputs the result of the heterogeneous fiber data whose format has been identified. The fiber signal scheduling unit shifts the heterogeneous fiber data whose format has not been identified clockwise through n sets of format identification modules. Then, the format identification module performs format identification on the shifted heterogeneous fiber data again. This process is repeated until the format of all m heterogeneous fiber data is identified, or until all the heterogeneous fiber data whose format has not been identified has been traversed through n sets of format identification modules, thus completing the format identification of this batch.

[0021] In some embodiments, the format recognition unit includes a high-speed format recognition unit and a low-speed format recognition unit.

[0022] In some embodiments, the high-speed format recognition unit includes several format recognition modules for recognizing high-speed OTN format heterogeneous optical fiber data; the low-speed format recognition unit includes several format recognition modules for recognizing low-speed OTN format, SDH format and ETH format heterogeneous optical fiber data.

[0023] Compared with the prior art, the beneficial effects of this application are:

[0024] 1. The parallel recognition architecture designed in this scheme supports the simultaneous output of n optical fiber signals to n sets of recognition modules with different formats, which shortens the switching time of optical fiber signals;

[0025] 2. The parallel recognition architecture designed in this scheme can recognize the format of n input optical fiber signals at one time, while serial recognition can only recognize one format type of one optical fiber signal at a time. The speed of parallel recognition in this application is n times that of serial recognition in the prior art.

[0026] 3. The parallel recognition architecture designed in this solution is highly scalable. The types of recognition modules can be expanded according to actual needs, including adding more types of OTN, SDH and ETH recognition modules, or increasing the number of the same recognition modules, all while maintaining a fast overall recognition speed.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] Optical fibers carry heterogeneous data of different formats and rates, including OTN, SDH, and ETH formats. OTN format heterogeneous fiber data includes various standard and non-standard types, while the rates range from 100Gbps, 10Gbps, to 2.5Gbps. Current technologies typically employ a serial identification scheme for identifying the format and rate of heterogeneous fiber data. (See reference...) Figure 1 In this scheme, the data is first input to the format one recognition module. If the module recognizes the data, it confirms that the format type of the input data is format one; if it cannot recognize it, the data is input to the format two recognition module. This process continues until the data has been processed by the format n recognition module.

[0036] Assuming there are n different format recognition modules, the shortest path for recognizing each input data is 1 (recognition successful in 1 attempt), and the longest path is n (recognition successful in n attempts). This approach results in a tedious and lengthy format recognition process with extremely low efficiency. Assuming n fiber optic signal data are connected, and there are n different format recognition modules, the number of attempts required to recognize the format type of all connected data when connecting fiber optic signals one by one is shown in Table 1 below:

[0037] Table 1

[0038]

[0039] Therefore, the parallel identification method for multi-path heterogeneous optical fiber data proposed in this embodiment includes the following steps:

[0040] S1: Output multiple heterogeneous fiber data in batches to n sets of format recognition modules for format recognition. The number of heterogeneous fiber data output in any batch is m, and m≤n.

[0041] S2: m heterogeneous fiber data are input one-to-one into m sets of format recognition modules, and format recognition is performed simultaneously;

[0042] S3: If the format of all m heterogeneous optical fiber data is identified, output the identification result and complete the format identification for this batch;

[0043] S4: If the format of m heterogeneous fiber data is not fully recognized, the m heterogeneous fiber data is shifted clockwise in n sets of format recognition modules, and then the format recognition of the shifted m heterogeneous fiber data is performed simultaneously again until the format of m heterogeneous fiber data is fully recognized, or until each heterogeneous fiber data has traversed all n sets of format recognition modules to complete the format recognition of this batch.

[0044] S5: Repeat steps S1 to S4 to complete the batch format recognition of multi-channel heterogeneous fiber optic data.

[0045] The format recognition process will be explained below through specific examples, taking m=n as an example:

[0046] 1. Send n heterogeneous fiber optic data streams to n sets of different format recognition modules;

[0047] 2. n sets of format recognition modules perform format recognition simultaneously;

[0048] 3. If all n heterogeneous fiber data are identified, the process ends, and the format identification of the n heterogeneous fiber data is completed in one identification.

[0049] 4. If the format of all n heterogeneous fiber data is not recognized, the n heterogeneous fiber data are switched and shifted clockwise before being output. That is, heterogeneous fiber data 1 is sent to format recognition module 2, heterogeneous fiber data 2 is sent to format recognition module 3, ... heterogeneous fiber data n-1 is sent to format recognition module n, and heterogeneous fiber data n is sent to recognition module 1. Then, the format recognition of the n heterogeneous fiber data after this switching output is performed again simultaneously.

[0050] 5. Repeat steps 2-4 until all n heterogeneous fiber data are identified (number of identifications ≤ n), or each heterogeneous fiber data traverses all n sets of format identification modules (number of identifications = n).

[0051] Assuming n fiber optic signal data are received, and there are n different format recognition modules, the number of iterations required to identify the format type of all received data in the case of parallel access is shown in Table 2 below:

[0052] Table 2

[0053]

[0054]

[0055] Under this parallel identification scheme, regardless of how the n fiber optic signal data are arranged, the number of identifications is a fixed value, which is 1 / n times the number of identifications in the serial scheme.

[0056] It should be noted that in step 4 above, although the format of all n heterogeneous fiber data cannot be identified at the same time in each identification process, the format of at least one heterogeneous fiber data may be identified. Therefore, in order to improve the efficiency of the identification process, the heterogeneous fiber data whose format has been identified does not need to be switched, output and identified again in each identification process, but it does not affect the scheduling and format identification process of other fiber signals.

[0057] Specifically, step S4 further includes: if the format of m heterogeneous fiber data is not fully identified, the result of the heterogeneous fiber data with the identified format is output, the heterogeneous fiber data with the unidentified format is shifted clockwise in n sets of format identification modules, and then the format of the shifted heterogeneous fiber data is simultaneously identified again. This process is repeated until the format of all m heterogeneous fiber data is identified, or until all the heterogeneous fiber data with the unidentified format is traversed through n sets of format identification modules to complete the format identification of this batch.

[0058] Furthermore, the heterogeneous optical fiber data can be in formats including OTN, SDH, and ETH.

[0059] Furthermore, the rates of the heterogeneous optical fiber data in the OTN format include 100G, 10G, and 2.5G.

[0060] Furthermore, the rates of the heterogeneous fiber data in the SDH format include 10G, 2.5G, 622M, and 155M.

[0061] Furthermore, the rates of the heterogeneous optical fiber data in the ETH format include 10G and 1G.

[0062] This embodiment proposes a parallel identification architecture for multi-path heterogeneous optical fiber data, referencing... Figure 2 ,include:

[0063] The format recognition unit includes n sets of format recognition modules, which are used to recognize the format of heterogeneous optical fiber data.

[0064] The fiber optic signal scheduling unit is used to output multiple heterogeneous fiber optic data in batches to n sets of format recognition modules for format recognition. The number of heterogeneous fiber optic data output in any batch is m, and m≤n.

[0065] If the format of all m heterogeneous optical fiber data is identified, the format identification module outputs the identification results respectively, thus completing the format identification of this batch;

[0066] If the format of m heterogeneous fiber data is not fully identified, the fiber signal scheduling unit will shift the m heterogeneous fiber data clockwise through n sets of format identification modules. Then, the format identification module will simultaneously identify the format of the shifted m heterogeneous fiber data again until the format of all m heterogeneous fiber data is identified, or until each heterogeneous fiber data has traversed all n sets of format identification modules to complete the format identification of this batch.

[0067] In this embodiment, the fiber optic signal scheduling unit is also used to simultaneously read the output light intensity of n fiber optic signals. To improve working efficiency, for fiber optic signals whose output light intensity is lower than a certain threshold detected by the fiber optic signal scheduling unit, there is no need to switch, output, and identify them again, but this does not affect the scheduling and format identification process of other fiber optic signals.

[0068] Furthermore, if the format of m heterogeneous fiber data is not fully identified, the format identification module outputs the result of the heterogeneous fiber data whose format has been identified. The fiber signal scheduling unit shifts the heterogeneous fiber data whose format has not been identified clockwise through n sets of format identification modules. Then, the format identification module performs format identification on the shifted heterogeneous fiber data again. This process is repeated until the format of all m heterogeneous fiber data is identified, or until all the heterogeneous fiber data whose format has not been identified has traversed all n sets of format identification modules, thus completing the format identification of this batch.

[0069] Furthermore, the format recognition unit includes a high-speed format recognition unit and a low-speed format recognition unit.

[0070] Furthermore, the high-speed format recognition unit includes several format recognition modules for recognizing high-speed OTN format heterogeneous optical fiber data; the low-speed format recognition unit includes several format recognition modules for recognizing low-speed OTN format, SDH format and ETH format heterogeneous optical fiber data.

[0071] refer to Figure 3In this embodiment, the high-speed format identification unit is responsible for identifying whether heterogeneous fiber data belongs to the 100G OTN type. Specifically, after four input data enters this module, they are simultaneously identified by four different format identification modules. If input data 1 is correctly identified by the 100G OTN format one identification module, then the format type of the input data is confirmed to be 100G OTN format one. The format types of input data 2-4 are obtained by analogy.

[0072] Furthermore, the types of 100G OTN identification modules can be expanded as needed to identify more types of 100G OTN fiber data.

[0073] refer to Figure 4 In this embodiment, the low-speed format recognition unit is responsible for identifying whether heterogeneous optical fiber data belongs to low-speed OTN, SDH, ETH, or other types.

[0074] Specifically, when input data enters the OTN identification module, if the signal type is OTN and the rate is 10G, the format type of the input data is confirmed to be 10G OTN; if the signal is OTN and the rate is 2.5G, the format type of the input data is confirmed to be 2.5G OTN.

[0075] The input data enters the SDH identification module, which determines whether it is one of 10G SDH, 2.G SDH, 622M SDH, or 155M SDH based on the synchronization lock status, and outputs the confirmation result.

[0076] Input data enters the ETH recognition module. If the signal type is ETH and the rate is 10G, the format of the input data is confirmed as 10G ETH; if the signal is ETH and the rate is 1G, the format of the input data is confirmed as 1G ETH.

[0077] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
